Power supply method for drone with multiple battery packs

Abstract

The invention relates to a power supply method for a drone with multiple battery packs. The drone includes a drone body, a drone power supply system includes a power module and a mainboard control module for controlling the operation of the power module, and the power module includes a plurality of battery assemblies which are connected in parallel. The method comprises the following steps that S1, the battery assemblies are numbered as the first battery assembly, the second battery assembly, ... and the nth battery assembly separately in a use order; S2, the motherboard control module startsthe first battery assembly according to the numbering sequence; S3, when the electric quantity of the first battery assembly is equal to or less than a critical electric quantity value, the mainboardcontrol module controls the first battery assembly to stop working and simultaneously starts the second battery assembly; S4, when the electric quantity of the second battery assembly is equal to or less than the critical electric quantity value, battery switching is performed according to the method in step S3 until the nth battery assembly is started; S5, when the remaining electric quantity ofthe nth battery assembly is equal to or less than a return electric quantity value, the mainboard control module controls the drone to automatically return.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a power supply method for an unmanned aerial vehicle with multiple battery packs. Background technique [0002] Common aircraft are usually divided into fixed-wing, helicopter and multi-rotor (four-rotor is the most mainstream). Before 2010, fixed-wing and helicopters basically occupied an absolute mainstream position in the fields of aerial photography and aircraft model sports. However, in the next few years, due to its excellent control performance, the multi-rotor quickly became a new star in the field of aerial photography and aircraft model sports. Because this product greatly reduces the difficulty and cost of aerial photography, it has won a large number of consumer groups and has become the best-selling product so far. [0003] The multi-rotor drone is also driven by the rotation of the motor to make the propeller generate lift and fly. For example, f...
